"Vongoosewink05-26-2017, 03:06 PMFor what it is worth, a buddy of mine and I did a tube-swap on a Wells Gardner med res in a Narc a couple years ago. We just used a standard TV tube, and swapped the yoke. It took a while to converge, but once properly adjusted neither of us could tell a difference - it looked great. Certainly better than the original burned-out and dim tube."

"modessitt05-16-2011, 08:51 PMThe tube has no bearing on whether it is standard or medium res. The difference is the yoke and how it is wound. I've done several repairs of medium-res chassis using a standard-res tube and just swapping the med-res yoke onto it.

As long as both tubes have the same neck pinout (CR-23 for the tube you mentioned - same as a G07, 4900, etc), you can use it as a tube swap if you use the original med-res yoke..."
